Signal’s methane analysers are designed for measurement in land fill applications.
Methane (CH4), the simplest aliphatic hydrocarbon, can be measured using infra-red absorption or the flame ionisation detector principle.
Infra-red is a widely used method with the major limitation for methane being a cross sensitivity to other hydrocarbon species. Infra-red is most appropriate for measuring methane at percentage levels in applications such as landfill or bioscience.
Flame ionisation is a non-selective technique for measuring total hydrocarbons. It can be used for methane where no other hydrocarbons are present or in conjunction with a specially designed catalyst used to oxidise non-methane hydrocarbons species contained in the sample.
Non Dispersive Infrared (NDIR) Multi-gas analysers are available in 1, 2, 3, 4 or 5 gas channel configurations, offering high levels of performance and flexibility. Options include CO, CO2, CH4, NO, N2O, SO2, HCl and O2.
Flame Ionisation Detector (FID) VOC analysers for gas purity, air separation, engine emmisions, combustion studies and process plant VOC abatement monitoring
Calibration is the process of establishing the relationship between the output of a measurement and a known input. In common with most measuring instruments, gas
Increasing political action on Climate Change is prompting a new requirement for process operators to improve the accuracy and reliability of greenhouse gas (GHG) emissions
